My family really enjoyed Disney's MGM Studios. Our family found the rides to be more thrilling than most of the ones at The Magical Kingdom. They especially enjoyed the Tower of Terror and Rock 'n Roller Coaster. The live action shows were saw were ok but I did not find them outstanding. The highlight of the day was definitely Fantasmic. This show was packed. We had special seating because of purchasing the dining/show package. Because we attended during the non-busy season this was a waste. Even those in the reserved section must arrive very early to get a good seat. The package limited the meal choices at the restaurant and although the food was great it we would have preferred full menu choices. If you are going during a busy time I would certainly purchase the package but otherwise don't waste the money.
As with everything Disney does, MGM Studios is perfectly themed and decorated. My family really enjoyed the day there and some even went back to hit a few rides again and go on some they missed.
